Utah Code § 41-6a-1106 expressly permits sidewalk and crosswalk cycling statewide, subject to the duties to yield the right-of-way to pedestrians, give an audible signal before overtaking and passing, and travel at a safe speed. Local governments may further restrict sidewalk riding by ordinance — Salt Lake City prohibits it in the downtown business district.
Utah's DUI statute (Utah Code § 41-6a-502) applies to anyone in actual physical control of a 'vehicle,' and Utah Code § 41-6a-1102 makes cyclists subject to the provisions of Title 41, Chapter 6a applicable to drivers of vehicles. Utah has the lowest BAC threshold in the United States at 0.05. A bicycle DUI carries the same statutory penalty range as an auto DUI — a class B misdemeanor on a first offense — and the conviction is reported as a DUI, which can trigger a driver-licence suspension even where no motor vehicle was involved.

Rear spec
Red reflector on the rear visible from all distances from 100 to 600 feet to the rear when directly in front of lawful lower-beam headlamps. A red rear lamp visible from 500 feet to the rear may be used in addition to the reflector.
Utah Code § 41-6a-1105(2) permits riding no more than two abreast except on paths or parts of roadways set aside for the exclusive use of bicycles. Persons riding two abreast may not impede the normal and reasonable movement of traffic and on a laned roadway shall ride within a single lane.
UDOT permits cycling on the shoulders of most Interstate segments in Utah (including substantial portions of I-15, I-70, I-80 and I-84) where no reasonable alternative parallel route exists. Specific urban segments along the Wasatch Front and several tunnels and bridges are signed prohibited; verify against UDOT bicycle-on-Interstate guidance before riding.
